| Research lines per researcher: | Characterization of early events related to the establishment of symbiosis between legumes and rhizobia. Identification and characterization of regulatory genes involved in the establishment of symbiosis between legumes and rhizobia. Identification of genetic regulators that control the legume-rhizobia symbiosis under conditions of phosphorus deficiency. |
The symbiosis between legumes and rhizobia is characterized by its high specificity, which is controlled through a molecular dialogue between the two symbiotic partners. Each signal triggers changes in the gene expression of both symbionts. In this laboratory, we are interested in understanding the early molecular events that determine the establishment of symbiosis and the development of nodules, which are the organs where biological nitrogen fixation takes place.
